我正在尝试使用 capistrano 将我的应用程序部署到 DigitalOcean 服务器。一切都会好起来的，接受我无法通过网络访问我的应用程序并看到“504 网关超时”。cap deploy 成功结束，但似乎 unicorn 没有启动。我将 multi_json 添加到我的 Gemfile 中并尝试了包更新。multi_json 1.8.0 在我的 gem 列表中，但在我的 /home/unicorn/log/unicorn.log 文件中，我可以看到以下内容：
E, [2013-09-20T07:53:54.994778 #26940] ERROR -- : Could not find multi_json-1.8.0 in any of the sources (Bundler::GemNotFound)
